Sapphire Lens Cell: 1 14500 ICR LithiumThis is a sapphire lens upgrade for the aluminum DC1 and DC2. They come with a mineral glass lens, but if your light sees any kind of rough environment this upgrade is highly recommended. Sapphire is the second hardest material in the world right after diamond. That means it's much less likely to get scratched. Please note that all non aluminum lights already come with sapphire lenses.
